[The ultrastructure of the inferior olivary complex in the ground squirrel (Citellus citellus L.). Age-related changes in the neurons].
The morphological characteristics of neurones in the lower olivary complex of ground squirrels at various age were studied by electron microscope. Some peculiarities in the ultrastructure of these neurones were described as the presence of prickles, fringes. Changes which occurred with advancement of age, were studied such as: an increase in the number of intranuclear inclusions, an accumulation of a large amount of elderly pigment under the form of lipofudcinis, lamellar bodies, myelin-like figures, vacuole-like bodies and nucleolus-like inclusions, called also nematosomes. On the basis of the analysis of ultrastructural peculiarities of neurones in the lower olivary complex of ground squirrels at various age the changes, which occurred during various functional states and during aging, are discussed.
